<p>PURPOSE: To enable lighting without using a transmitter for remote control by providing a sensing part operating and outputting by sound on the controller of a lighting fixture, etc. CONSTITUTION: A sound pressure sensing circuit part 26 is composed of the time limit oscillation circuit and output circuit provided with a sound pressure sensing part 24. The sound sensing part 24 uses a piezoelectric element which is easy to synchronize with impact sound such as clapping sound, etc. When the impact sound such as clapping sound, etc., now acts on the sound pressure sensing part 24 through the sound pressure intake provided on the main body of a controller, the time limit oscillation circuit of the sound pressure sensing circuit part 26 operates and outputs are shown on the output circuit for fixed time. The output shown in the sound pressure sensing circuit 26 operates a power-on reset circuit 22, a counter part 18 is set to be a first stage without fail, a state that a signal is transmitted to a power source switch part 19 is made and a lighting fixture, etc., is turned on. Therefore, lighting becomes possible without using a transmitter for remote control.</p> |
